Egocentric BVCs, KeyError: 'vel'

[CYHSM]

Thanks for the amazing toolbox. I was just trying to create some egocentric BVCs and I received the following error: Code:

BVCs = BoundaryVectorCells(Ag, params={"n": num_neurons, "color": "C3", "reference_frame": "egocentric"})

Error:

Thanks again for pointing it out. Fixed this.

It should be ready to go if you reinstall RatInABox from dev branch now. This will get merged to 1.x and PyPI published at next version sometime quite soon.

The latest version of RatInABox (v1.1.0 on PyPI) should include this fix.

Could you confirm you don't experience any issues then I'll close

Pretty sure this is fixed and pushed to the new version 1.1.0. Reopen if necessary!
